How to Fix Windows 11 disk usage 100% or high (Solved!)

Before moving around the reasons and solutions, first of all, let’s see what is disk usage. Disk usage in Operating system is the portion of computer storage that HDD or SSD is reading and writing. In normal state, the usage remains under 10% and you can check this easily from Task Manager. But when certain abnormalities occur the percentage value of disk usage shoots up in Task Manager. So in this post, you will see ways to fix Windows 11 disk usage 100% or high.

When windows 11 disk 100 percent problem appears, the computer will become slow, programs will open late after clicking them, and games will hang repeatedly. This is really frustrating and can make your Windows 11 experience worse. There are a few reasons leading the disk usage to go higher such as too many startup programs, obsolete driver software, virus, some services monopolizing the disk or so many applications running at the same time. Additionally, Windows search index, negligible RAM to fit in with SysMain and inability of HDD to leverage native command are potential causes too. However, such high disk usage issues can be fixed if you hit the right points with effective workarounds.

Windows 11 Disk usage 100%

Here is how to fix Windows 11 disk usage 100% –

1] Reboot Windows 11

Whenever a problem arises in Windows 11, the resolution that gets priority over any other is restarting the device. This is simple and not likely to resolve the underlying root causes in most cases but will definitely boost up the system. If you are having high disk usage issue, rebooting will bring down it to lower level.

8. Check if the Disk usage has been lowered down.

2] Perform a check for malware to fix System high disk usage

Protection against viruses is mandatory nowadays as it could also lead to high Disk usage of the system. Malware is a designed software to seize your machine and eventually steal necessary data from it. Moreover, these will cause severe harm to the system components by corrupting them.

Malware includes Trojan horses, adware, worms, ransomware, and spyware that can easily keep their identity hidden. Without a powerful security suite, your computer can be a host for these bugs and get into trouble. Windows Security is provided with the OS has a very powerful built structure which can deal with the malware perfectly. In order to fix the Windows 11 disk usage 100%, do virus scan in your system and eliminate the threats if found any. Follow the below guidelines to scan and dismiss viruses –

1. Once traced out viruses, you will be given options to take necessary actions. Follow the guidelines on the screen to resolve them.
2. Restart Windows 11 to make the changes effective.

3] Reset Virtual memory to solve Disk at 100% for no reason

Virtual memory in Windows 11 allows the OS to expiate if the physical RAM falls into indebtedness. It will momentarily transfer the additional data from virtual memory to the system storage. This is also a very much powerful management idea in recent times to control multitasking and the flexibility even the RAM of the device is a bit low.

Virtual Memory in Windows 11 can lead to some trouble despite being a great feature. Oftentimes it triggers Windows 11 disk usage 100% issue from errors in the pagefile.sys file. If your hard drive is not so old, resetting the virtual memory can fix this issue. To reset, follow the below guidelines –

6. Once done, restart the Windows 11 device and check if the issue is resolved.

4] Change Power plan to High performance

In order to improve battery life in laptops, Windows choose to set the Power plan into Balanced. This is very much prone to increase the disk usage which can be settled down by shifting into High-performance mode. The idea will consume more battery power of course but thanks to the modern manufacturers to provide the battery with more capacity. Hence if you are having Windows 11 disk usage 100% issue, change the power plan settings. For that, follow the below guidelines –

SysMain is the present name of Superfetch service that helps to pre-load the application commonly used in Windows. This also ensures the enhancement of the system performance. Additionally, this service can keep a record of apps you use on specific days in a week or in other patterns to optimize the apps open accordingly.

Some users have come up with Windows 11 disk usage 100% issue in their system and when SysMain remains enabled. Despite of being a very lucrative feature in medium and high end configuration computers, this service does not give the best outcome in slightly lower end devices. A machine with relatively low RAM and frequency, SysMain will transfer the load from RAM to VRAM. This will make the situation even worse and increase disk usage to a higher percentage. In order to fix the issue, disable the service now going through below steps –

1. Press – Windows + X.
2. Select – Run.
3. In the command box, type – services.msc.
